|Route outline (key)|
B4288 was the designation assigned – from 1935, or some time thereafter, until at least 1982 – to a route linking the A48 at St Mellons in Monmouthshire to the A468 at Bassaleg via Began and Michaelston-y-Fedw.
This road, twisty and very narrow in places, is currently unclassified apart from its first 700 yards (650 metres), which now form part of the B4562.
